Hauv kev ua haujlwm siab -, cov khoom siv zog ib leeg yeej tsis txaus. Dab tsi tiag tiag txiav txim siab txog kev ntseeg siab yog seb cov qauv sab hauv ntawm cov hlau tuaj yeem tiv taus kev ntxhov siab, kub, siab, thiab ntev - lub sij hawm qaug zog. Yog vim li cas titanium forgings tau dhau los ua qhov kev xaiv zoo tshaj plaws rau aerospace, kev kho mob, marine, thiab kev siv hluav taws xob.
Forging yog dab tsi?
Los ntawm kev txhais, forging yog txheej txheem kev tsim khoom uas siv rau lub tshuab hlau siv cov khoom siv forging, ua rau cov yas deformation thiab ua tiav cov duab uas xav tau, qhov loj me, thiab kev ua haujlwm zoo. Nws yog ib qho ntawm cov ceg tseem ceeb ntawm cov hlau ua tshuab.
Txawm li cas los xij, los ntawm kev tsim khoom, forging tsis yog tsuas yog hais txog kev tsim cov hlau - nws yog kev tsim kho kom tiav ntawm cov khoom siv.
Vim Li Cas Koj Yuav Tsum Tau Forging?
Thaum lub sij hawm cov txheej txheem hlau smelting, defects xws li porosity thiab coarse cam khwb cia nplej yog tsis muaj. Tus nqi tseem ceeb ntawm forging yog tias nws tuaj yeem:
- Tshem tawm cov teeb meem sab hauv xws li casting porosity
- Optimize thiab kho cov microstructure
- Ua kom tsis tu ncua hlau nplej ntws
Tias yog vim li cas cov khoom tseem ceeb siv nyob rau hauv siab -load, siab - cuam tshuam, los yog huab cua ib puag ncig - xws li cov qauv aerospace, cov khoom siv hluav taws xob, thiab cov khoom siv kho mob - feem ntau yog tsim los ntawm forgings es tsis yog castings lossis welded qhov chaw.
Lub Evolution ntawm Forging: Los ntawm Blacksmithing rau Precision Engineering
Thaum koj xav txog kev forging, koj tuaj yeem pom ib tus kws ntaus hlau rau cov hlau nplaum rau hauv cov duab. Tsoos tes forging hnub rov qab ntau tshaj 2,000 xyoo nyob rau hauv ancient Tuam Tshoj.
Tom qab Industrial Revolution, forging maj mam ua mechanized. Niaj hnub no, niaj hnub forging tau hloov zuj zus mus rau hauv kev tswj hwm engineering kev qhuab qhia uas suav nrog:
- Kev tswj qhov kub thiab txias
- Kev tswj siab
- Microstructure tswj
Niaj hnub no forging yog zoo li "cov ntaub ntawv phais." Txhua qhov kub thiab txias, txhua tuj ntawm lub siab, thiab txhua txoj kev deformation yuav tsum raug tsim thiab tswj tau zoo.
Txawm tias me me sib txawv tuaj yeem ua rau cov khoom tsis ua haujlwm.
Vim li cas Ti-6Al-4V dhau los ua Core Titanium Alloy
Raws li kev siv thev naus laus zis tau dhau los, cov neeg tsim khoom tau maj mam hloov los ntawm cov pa steels mus rau qib siab -kev ua tau zoo alloys.
Ntawm lawv,Ti-6Al-4V(Qib 5 titanium) tau los ua cov khoom tseem ceeb hauv kev lag luam siab - kawg rau cov laj thawj hauv qab no:
- Siab zog
- Zoo heev ductility thiab forgeability
- Zoo corrosion kuj
- Biocompatibility zoo heev
Yog li ntawd, nws yog dav siv nyob rau hauv:
- Aerospace engine Cheebtsam
- Kev kho mob cog xws li cov pob qij txha
- Cov khoom siv tshuaj ua haujlwm
- Deep-sea engineering systems
Txawm li cas los xij, ib qho tseem ceeb yuav tsum tau hais txog:
Qhov kawg kev ua tau zoo ntawm Ti-6Al-4V nyob ntawm tsis tsuas yog nws cov tshuaj muaj pes tsawg leeg, tab sis kuj nyob rau hauv cov txheej txheem forging nws tus kheej.
Forging lov cov ntxhib cam khwb cia nplej thiab txhawb nqa recrystallization, tsim kom zoo thiab zoo ib yam equiaxed microstructure. Yog tsis muaj cov txheej txheem no, txawm tias siab tshaj - zoo alloy muaj pes tsawg leeg tsis tuaj yeem xa nws cov peev txheej ua tau zoo.
Peb Cov kauj ruam tseem ceeb ntawm Titanium Qhib - Tuag Forging
1. Kev npaj khoom siv
Tom qab melting, titanium ingots yog machined rau hauv huv billets, thiab cov riser seem raug tshem tawm kom ntseeg tau zoo nyob rau hauv.
2. Cua sov: Qhov sib txawv ntawm 10℃tuaj yeem yog qhov tseem ceeb
Titanium alloys feem ntau rhuab mus rau 900℃-950℃(hauv cheeb tsam + theem) rau forging.
Rau Ti-6Al-4V, beta transus kub yog kwv yees li 980℃-1010 degree.
Titanium yog rhiab heev rau qhov kub thiab txias. Nws raug txwv nruj kom dhau thaj tsam beta theem - ib zaug qhov no tshwm sim, cov nplej loj hlob sai sai, ua rau cov khoom tsis zoo mus tas li.
Raws li peb cov kev paub dhau los, 3-tuj, φ600mm Qib 5 titanium ingot yuav tsum tau kwv yees li 5.5 teev ntawm lub sijhawm so tom qab ncav cuag lub hom phiaj kub.
Cov txheej txheem yog nruj me ntsis tswj nyob rau hauv theem:
- Cua sov
- Mus txog qhov kub thiab txias
- Soaking
- Rauv tawm
Txhua batch yog kaw nyob rau hauv ib tug forging kub cav, nrog rau tag nrho cov cua kub nkhaus.
Nyob rau hauv titanium forging, ± 10℃tsis yog ib qho kev sib txawv ntawm kev tso cai - nws yog qhov tseem ceeb:
- Siab dhau: coarse nplej, txo lub zog, qis ductility
- Tsawg dhau: tsis zoo plasticity, tawg thaum forging
Qhov no yog vim li cas peb siv dual -kub kub tswj thiab tag nrho traceability rau txhua billet lub thermal keeb kwm.
3. Forging: "Kev ntxhov siab thiab kos duab" yog qhov tseem ceeb ntawm Microstructure Reconstruction
Muab cov rhuab billet tso rau hauv lub tshuab forging thiab ua tib zoo tswj ob qho tib si kub thiab deformation (feem ntau 30% -50%). Cov txheej txheem tsis yog los ua kom tiav cov duab kawg hauv ib kauj ruam.
Kev ua haujlwm ua ntu zus yog: kos duab ua ntej, tom qab ntawd chim siab, rov ua dua 2-3 lub voj voog ("ob mus rau peb qhov kev ntxhov siab thiab kos duab voj voog").
chim siab
Upsetting compresses lub billet, ua rau nws luv thiab thicker. Qhov siab txo qis thaum tus ntoo khaub lig- ntu ntu nce thiab ua kom zoo sib xws.
Kev kos duab
Kos duab elongates thiab txo cov thickness ntawm lub billet. Tus ntoo khaub lig- ntu ntu txo qis thaum qhov ntev nce.
Lub voj voog no rov ua dua 2-3 zaug. Lub ntsiab ntawm txoj kev yog:
Dendritic cam khwb cia cov nplej tau tawg tag → recrystallization tshwm sim → ib qho qauv zoo equiaxed nplej yog tsim.
Cov txheej txheem no feem ntau piav raws li kev hloov pauv ntawm metallurgical thiab microstructural refinement ntawm cov khoom.
Peb Qhov Tseem Ceeb Tseem Ceeb hauv Titanium Alloy Forging
1. Precise Temperature Control
Qhov zoo tshaj plaws forging ntau rau titanium alloys yog feem ntau30℃-50 degreehauv qab ntawm beta transus kub.
Lub qhov rais txheej txheem yog qhov nqaim heev thiab yuav tsum tau muaj qhov tseeb ntawm lub tshuab hluav taws xob tswj.
2. Loj Hydraulic Xovxwm Capacity
Hauv titanium forging, ntau lub zog tsis yog ib txwm zoo dua.
Dab tsi tseem ceeb yog uniform, tswj deformation ntawm qhov chaw mus rau lub hauv paus.
Piv nrog rauj forging, hydraulic presses muab:
- qeeb thiab ntau yam deformation
- Internal ceev zoo dua
- Txo kev cais tawm
- Tsawg qhov kev pheej hmoo ntawm kev tawg sab hauv
- Ntau qhov sib xws mechanical zog
3. Pab neeg sib koom tes
Titanium forging tsis yog ib qho - tus neeg ua haujlwm txheej txheem tab sis kev ua haujlwm tas mus li, ntau - tus neeg ua haujlwm.
Los ntawm kev ntsuas kub, tuav billet, thiab lub cub tawg hloov mus rau forging tswj thiab ntsuas qhov ntev, txhua kauj ruam yuav tsum tau ua kom nruj.
Thaum qhov kub thiab txias, txawm tias ncua sij hawm ntawm ob peb feeb tuaj yeem thawb cov khoom tawm sab nraum lub qhov rais ua haujlwm, cuam tshuam ncaj qha rau qhov kawg.
Yog li ntawd, kev sib koom tes ruaj khov pab pawg tsuas yog ib qho tseem ceeb xws li cov cuab yeej muaj peev xwm.
Vim li cas thiaj yuav tsum tau kho cua sov tom qab forging
Forging ib leeg tsis ua kom tiav cov khoom.
Tom qab forging, titanium cov ntaub ntawv tseem yuav muaj:
- Residual stress
- Tsis ruaj tsis khov microstructure
- Tsis yog- tsis tu ncua theem faib
Kev kho cua sov yuav tsum tau:
- Txo kev ntxhov siab sab hauv
- Stabilize + theem qauv
- Sib npaug zog, ductility, thiab toughness
Yog tsis muaj kev kho cua sov, ib qho forged titanium tivthaiv tseem yuav tsum tau suav tias yog ib nrab - cov khoom tiav.
